It works fine.However I read somewhere that this undocumented procedure might be a deprecated feature of SQL Server. (still available in my SQL Server 2012 SSRS)So you should not get [b]too attached[/b] to it.meanwhile...I would like to use this e.g. in my SQL Agent Jobs.For this I need to mimimze my maintenance task, as I am not always around when someone is modifing the cache configurations (e.g. deleting one cache config and creating a new one), I don't know if the EventData-IDs might have changed.So I created a little procedure that fetches all the subscriptions of an desired type (e.g. RefreshCache) and creates an AddEvent-Call for it.I kept it simple, but feel free to put more effort into it. You can probably filter subscriptions that are still active and so on...As it is encapsulated there is a change to modify what is triggered one's M$ replaces the AddEvent-Procedure with something new.

Hover over the report or shared dataset, and click the drop-down arrow. In the drop-down list, click Manage. The General properties page opens. Click the Cache Refresh Plan tab. To create a new cache plan, click New Cache Refresh Plan. NoteNote You must enable and start the SQL Server Agent service to create a cache refresh plan. To create a copy of a cache plan and then customize it, click New from Existing.

As my DWH is depending on a lot of other systems the jobs to process the data for the reports do not finish on the exact same time.However I would like to avoid to schedule the expiration of the cache with a time buffer to be sure the data is ready of the report.Instead I would prefer to trigger the expiration through the Agent-Job that is creating the data. It nows best, when its ready ;-)Is there a way to expire the cache/force to refresh through an SQL statement/or a procedure call?MitchThu, 14 Feb 2013 01:58:26 GMTchristian_t
